X39 + X49
The Athlete Protocol
The two patches LifeWave designed to be worn together — a general-repair foundation paired with a performance- and stamina-focused layer for training days.
Two Different Copper Peptides
X39 and X49 are designed around two different copper peptides — X39 targets GHK-Cu, a broad repair-and-renewal peptide, while X49 targets AHK-Cu, a peptide LifeWave associates specifically with muscle health, physical endurance, and strength.
Neither patch delivers anything through the skin — both work by reflecting the body's own infrared light back into it. Worn together, they're designed to combine a general-wellness foundation with a performance-specific layer, rather than duplicating the same signal twice. LifeWave also sells the two together as an official X39 & X49 Performance Bundle.
In Plain Terms
- •Two different copper peptides, not the same signal twice
- •Light reflection only — nothing crosses into the bloodstream
- •Sold together by LifeWave as an official Performance Bundle
- •Community nickname: the "Shred Protocol" — not official LifeWave terminology
What the Published X49 Study Found
Connor et al., International Journal of Sports and Exercise Medicine (2023)
22 men aged 40–80 wore the X49 patch 8–12 hours a day for 60 days while doing 20 minutes of exercise three times a week (19 completed the study). Standard fitness measures showed strength improvements ranging from roughly 31% to 70% by day 60.
- •Small sample (19 completers) — not yet a large-scale trial
- •Funded by LifeWave Corp, though conducted at an outside laboratory
- •Paired with a light exercise routine — not tested as a passive-only intervention
How Athletes Typically Use the Stack
Apply both patches to clean, dry skin in the morning. Both are worn during the day, generally up to 12 hours, then removed and replaced with fresh patches the next day. In the published X49 study, patches were paired with a light, regular exercise routine rather than worn passively.
Exact placement matters. X39 goes on GV14 (the bony bump at the base of the back of the neck) and X49 on CV6 (two finger widths below the belly button). Our patch user guide walks through every placement point, or reach out to us for personalized guidance.
Need More Energy On Training Days?
Some athletes add Energy Enhancer to the X39 + X49 stack as needed on higher-demand days, rather than wearing it daily — it's an optional third layer, not a required part of the core stack.
